Sample questions

1. Which of the following landforms is created by the deposition of sediment at the mouth of a river as it flows into a larger body of water like an ocean or sea?

   1. Meander
   2. Mountain
   3. Delta
   4. Riverbed
   Show answer

   Answer: C. Delta

   A delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This deposition causes the river to spread out and slow down, leading to the formation of a triangular or fan-shaped area of land.

2. What is the primary force that shapes mountains over geological time?

   1. Wind erosion
   2. Glacial action
   3. Tectonic plate movement
   4. River erosion
   Show answer

   Answer: C. Tectonic plate movement

   Mountains are primarily formed by large-scale geological processes involving the movement and collision of Earth's tectonic plates. These movements can cause the crust to buckle, fold, and uplift, creating mountain ranges. While erosion by wind, glaciers, and rivers shapes mountains after they are formed, tectonic activity is the primary force behind their creation.

3. The process of a river carrying sediment, such as sand, silt, and pebbles, is known as:

   1. Corrasion
   2. Corrosion
   3. Transportation
   4. Hydraulic action
   Show answer

   Answer: C. Transportation

   Transportation is the movement of eroded material by the river's flow. Corrasion (or abrasion) is when the river uses its load to grind away the banks and bed. Corrosion is the chemical dissolution of rocks. Hydraulic action is the force of the water itself.

4. The process that causes the sinuous curves in a river's course is predominantly:

   1. Deposition on the outer bank
   2. Erosion on the inner bank
   3. Both erosion on the outer bank and deposition on the inner bank
   4. Uniform erosion along the entire riverbed
   Show answer

   Answer: C. Both erosion on the outer bank and deposition on the inner bank

   Meanders are formed by the combined processes of erosion and deposition. The outer bank of a meander experiences faster water flow and thus more erosion, while the inner bank experiences slower flow and deposition.

5. Which of these is NOT a typical feature found in the lower course of a river?

   1. Meanders
   2. Floodplains
   3. Deltas
   4. V-shaped valleys
   Show answer

   Answer: D. V-shaped valleys

   V-shaped valleys are characteristic of the upper course of a river due to steep gradients and vertical erosion. The lower course is typically characterized by meanders, wide floodplains, and deltas formed by deposition.
